How To: Fingerprint-lock apps without a fingerprint scanner on Android

Biometrics is one of the best security options for locking digital content. In fact, it’s miles ahead any PIN, pattern or passphrase you could set, since your fingerprint is obviously way harder to crack than any kind of character string.

For those owning an Android device equipped with a fingerprint scanner, locking apps (or the phone) using this method is readily available. Even so, we’ve got a handy app for you that lets you fingerprint-lock your apps even if your phone doesn’t have a fingerprint scanner.

All it needs (and we’re pretty sure it can’t be called a smartphone if it doesn’t) is a camera. Here’s what you need to do, in order to unlock this functionality on your Android phone or tablet.

The application in question is called Fingerprint AppLock (Real) and it lets you lock any app you want using your fingerprint. It uses the rear camera and image processing to ‘scan’ your fingerprint.
